Probably #1 in my opinion. MCs all have such magnificent personal growth, especially the male lead. He has reasons being an el'douche he was in the beginning. Female lead also steps down her high horse later, it's gets annoying in the beginning but if you can get past it good. The mystery of how she ends up here is really frustrating good and mysterious and sits at the back your mind the entire time you're reading. It's still unknown at where I'm at currently which is chapter 286. I really hope this gets finished and doesn't get dropped like normal. And I'm very thankful for the scanslation team, Immoral Updates for updating this frequently and they do such a good job at translating and editing.
